Duo is enforcing updated requirements that may prevent authentication on devices running outdated operating systems or older versions of the Duo Mobile app. This article explains how to update iOS or Android and update the Duo Mobile app (including tablets or secondary devices) to avoid login issues, and outlines what to do if your device cannot be updated.

Update Your Phone OS and Duo Mobile App to Avoid Authentication Issues

Summary: Duo is enforcing updated requirements. To avoid authentication issues, make sure your phone’s operating system (iOS/Android) and the Duo Mobile app are up to date.

Who this is for

What you need to do

1. Update your phone’s operating system (OS) (iOS or Android).
2. Update the Duo Mobile app from your device’s app store.
3. If you use Duo on a tablet or secondary device, update that device too.

Step 1: Update your phone OS

iPhone / iPad (iOS / iPadOS)

• Follow Apple’s steps to update iOS/iPadOS: Update your iPhone or iPad (Apple Support)

Android

• Follow Google’s steps to check for and install Android system updates: Check & update your Android version (Google Support)

If you can’t update
